World Top 100 Rankings - 7 January 2013

The ATP World Tour releases new rankings on almost every Monday during the tennis season. The rankings represent each player's results for the past 52 weeks. Ranking points are awarded based on how far a player advances in a tournament and how many points are available for that tournament. Grand Slam tournaments yield the most ranking points per round, followed by Masters 1000 tournaments. For more on how the ATP Tour and ITF men's tennis work, see The Structure of Men's Pro Tennis.
